Paper Abstract

Anodic sulfides were grown on HgCdTe using different electrolyte concentrations and current densities. These sulfide films were characterized by film thickness, refractive index, and composition depth profile. The results demonstrate a strong dependence of film properties on the extent of electrolyte polarization. By enhancing the polarization effect during anodization high quality sulfide/HgCdTe interfaces, and thus satisfactory electrical characteristics, are obtained.
